Autosave - lost page (3 posts)

Spent more than 4 hours building a page on my site showing my online products to buy and installed paypal cart. Connection must have been slow so it autosaved, so i clicked on the latest version. But when I opened it the page was empty !!!! :(

How do i get access to autosave and open a saved document just before that last autosave to retrieve my work??
